IMPROVEMENT IN BOTTLE-STOPPRS.

Specification forming part of Letters Patent No. 102, 3419, dated April26, 1870.

y ence being had to the accompanying drawings,

making a portion of this specification, in

' whichthe parts when the bottle is opened.

Similar letters of reference indicate correspondin g parts in all thefigures.

The object of this invention is to provide a cheap and simplebottle-stopper, which may be easily manipulated to open or close thebottle, which will insure the hermetical sealingot the .bottle whenapplied for use, and which will not be liable to displacement by theinternal pressure consequent upon the lgeneration of gases from thecontents of the bottle.

The invention consists in a novel construction ot' the stopper; wherebythese results are e'ectually secured.

To enable others to understand the nature and operation of ourinvention, We Will proceed to describe it With reference to thedrawings.

A represents the neck of the bottle, above .which is the usual bulgingor enlarged portion, B, surrounding the mouth or orice of the same.

Around the neck A is fastened an annular Wire or circlet, G, which maybe made in any appropriate manner, but which, at opposite sides of theneck, must be so shaped as to permit the pivoting` thereto at one sideof the link C, at the other of the hook or catch D.

The upper end of the link C has pivoted or otherwise attached to it, bya lexible connection, a circular plate, E, of sufcient size to cover thetop of the bottle, and having secured to its under or 'inner side aconical india-rubber pad, F. The attachment of this pad to the plate maybe most readily secured by a central rivet, a.

At a point near its edge opposite that at Which it is attached to thelink C the plate E has formed in its upper surface a notch, recess, orindentation, b, as shownv in Fig. 2.

In using the stopper to close the bottle the plate E is brought over,With its conical pad F fitting into the mouth of the bottle, asrepresented in Fig. 2. The spur c of the hook or catch I) is thenbrought over the sloping surface a at thc adjacent edge of the plate Euntil its sharp point b passes into the notch b.

The surface a' facilitates the passage of the point b to the notch7 andthe latter`insures the retention in place of the hook. This done, thehook, in conjunction with the link C, holds the plate so that it firmlypresses the conical pad into the mouth ofthe bottle, and therebyetfectually closes, stops, or seals the same..

When it is desired to open the bottle, it is only necessary to force thehook C laterally outward until its hold upon the plate is re leased,whereupon the latter, with its pad, may be swung` out of the way, asShown iu Fig. 3. Meanwhile, the holdingofthepoint b of the hook on thenotch b prevents any displacement of the hook from ordinary accidentalcauses, and the action of the parts above specitied is sufcientto holdthe stopper in place against any pressure from within-such, for example,as occurs from the generation of carbonio-acid gas during thefermentation of various bottled liquors.

Having thus described o'ur invention, What we claim as new, and desireto secure by Letters'Patent, is-

The combination of the hook D, constructed with the point b', with thepad-carrying plate E of the link C, when such plate is formed with thenotch b and inclined surfacea,sub stanti-ally as and for the purposeherein set forth.
